Stop hunting in trading describes price spiking just through an obvious level, triggering the stop-loss orders gathered there, then snapping back. It feels personal when your stop is the one hit, but it is better understood as market behaviour: many traders put their stops in the same places, and a cluster of orders can speed price up once it is reached.
Quick answer: what is stop hunting in trading?
Stop hunting is a quick move through a level where many stop-loss orders sit, often just beyond a round number or a recent high or low. The triggered stops add to the move, which can then reverse. You cope by placing stops beyond the level that proves your idea wrong, adding a buffer and sizing the trade from that stop.
Why stop orders cluster where they do
Most traders are taught the same rule: put the stop just below support or just above resistance. Add round numbers, which people prefer for orders, and you get many stops sitting a few pips beyond the same obvious prices.
There is real evidence for this. Carol Osler’s Federal Reserve Bank of New York research on stop-loss orders and price cascades studied the order book of a large dealing bank between 1999 and 2000. It found that stop-loss sell orders cluster just below round numbers and stop-loss buy orders just above them, while take-profit orders sit more often on the round number itself.
Why a cluster speeds price up
A stop-loss sell order becomes a market sell order once price falls to it. If hundreds of them sit just below a level, each fill can push price lower and reach the next batch. Osler called these chains “price cascades”, and found exchange rates moved unusually fast once they reached levels where stops cluster.
The paper is careful to say statistics cannot prove cause and effect, and its data comes from currency markets more than two decades ago. We treat it as a sound explanation of a pattern traders still see, not as a law.
Is stop hunting deliberate?
Many forum posts blame brokers or “smart money” for hunting retail stops. We have not seen evidence that a broker deliberately moves prices to trigger its own clients’ stops, so we do not make that claim.
What can be shown is simpler. Large traders need someone to trade with, and a cluster of stops is a pool of orders. Whether a spike is someone pushing for those orders or just ordinary selling meeting a crowd of stops, the result on your chart looks the same, and your defence is the same.
Wick-throughs vs real breaks
A stop run usually leaves a long wick through the level and a close back on the original side. A genuine break tends to close beyond the level and keep going. The difference often only shows once the candle has closed.
| Sign | Wick-through (stop run) | Real break |
|---|---|---|
| Candle close | Back inside the level | Beyond the level |
| Follow-through | Little or none | Next candles extend the move |
| Speed after the spike | Sharp return | Pause, then continuation |
| Market structure | Trend still intact | New lower low or higher high |
| Retest | Level holds again | Old level now acts against price |
Our guide on how to identify market structure explains which highs and lows count when judging that last row. For the breakout side of the same picture, read how to avoid false breakouts.
How to place stops so they are harder to run
You cannot stop price from reaching a cluster. You can avoid being part of the most obvious one, and make sure that if you are stopped out, your idea was genuinely wrong.
- Find the level that proves you wrong. For a long trade, usually the swing low or the far edge of the zone, not the nearest round number.
- Add a buffer. Place the stop a little beyond that level, allowing for the spread and normal noise.
- Avoid the exact obvious pip. If the level is a round number, keep clear of the few pips just beyond it.
- Size the trade from the stop. Work out the stake so the £ loss at the stop matches your risk rule.
Our article on where to place a stop loss with price action covers each setup in detail, and ranking key levels by strength helps you see which ones attract the most orders.
Why mental stops are not the answer
Some traders stop using real stop orders so nobody can “see” them. That swaps a small, planned loss for the risk of freezing as price runs, which is usually far worse.
A worked example: buffer and sizing
Example: on a hypothetical £5,000 account risking 1%, the most you plan to lose is £50. A currency pair is in an uptrend and pulls back to buy at 1.0830. The swing low is 1.0785, and 1.0800 is a round number just above it.
The obvious stop is 1.0795, just under the round number, where Osler’s research suggests stops gather. Instead, the stop goes below the swing low that would prove the trend wrong, with a 10-pip buffer, at 1.0775.
That is 55 pips of risk, so £50 ÷ 55 is about £0.91 per pip, rounded down to £0.90. If stopped at its level, the loss is £49.50. Spread bets and CFDs are leveraged, so a gap or fast market can fill the stop further away and cost more; our guide to calculating position size for spread bets and CFDs sets out the method.
Once the trade moves in your favour, moving the stop behind new swing lows follows the same logic, as our trailing stop loss strategy explains.
Common mistakes
- Stops a pip beyond the obvious level. That is exactly where the crowd’s stops sit.
- Widening the stop without cutting size. A wider stop must mean a smaller stake.
- Chasing the reversal. Jumping in after every wick is guessing, not a setup.
- Blaming the broker for every stop-out. It stops you reviewing whether the stop was badly placed.
- Trading thin hours. Quiet sessions make spikes through levels more likely.
Frequently asked questions
Is stop hunting real?
Fast moves through levels where stops cluster are well documented, including in New York Fed research on currency markets. Whether any single spike was deliberate cannot usually be known from a retail chart.
Do brokers hunt your stop losses?
We have not seen evidence that brokers deliberately move prices to trigger clients’ stops. Stop runs are better explained by many orders sitting at the same obvious levels.
What is a liquidity grab?
It is another name for the same behaviour: price reaching a pool of resting orders, often stops beyond a high or low, before reversing. The term is popular in “smart money” trading circles, but the mechanism is the same.
How far beyond a level should a stop go?
There is no fixed number of pips. We use the level that proves the idea wrong, plus enough buffer to cover the spread and the market’s normal noise, then size the trade to fit.
Next steps
Review your last ten stop-outs and note how many sat within a few pips of a round number or an obvious high or low. Then rework those stops using the steps above, and set your risk with our guide to how much to risk per trade.
